Diagnostic Dump to Tape

Diagnostic Dump to Tape
Whenever an error occurs that creates diagnostic dump data, the red service
and green activity indicators on the operator panel flash, to indicate new
diagnostic data is being saved (dumped) to the EEPROM. Once the data is
saved, the indicators stop flashing. The display now alternates between an
* ,
and xxxx:Dmpyy , to indicate that a new uncollected dump is present and is
available to download (collect) to tape or electronic files.
Note: The notation “ xxxx ” is the FSC of the fault that caused the dump, and yy =
total number of uncollected dumps in the EEPROM .
Use the following procedure to collect diagnostic dump data from the drive
EEPROM to a specially formatted, write-enabled tape cartridge. If formatting a
tape is required, see
“Format a Diagnostic Dump Tape” on page 4-10.
The dump to tape operation does not overwrite dumps already on the tape.
New dumps append to earlier dumps already on the tape.
To collect a diagnostic dump to tape:
1. Ask the operator to make sure the drive does not have I/O to/from the host.
2. Load a write-enabled, formatted dump tape in the drive.
Notes:
• Data is automatically written to the tape from the drive’s EEPROM.
• While data is being written to the tape, the green activity indicator
flashes.
• When the process is done, the dump tape cartridge ejects.
• If DmpWrFailx displays (where x=1 or 2), an error has occurred.
See Table 7-2 on page 7-3 .
3. Remove the dump tape cartridge.
4. If drive is Offline, return it to Online.
5. Exit menu system.
Note: A steady * should display after exiting.
6. Inform the operator that the drive is ready.
